RDS supports a sophisticated 3D simulator with a Physics engine and an Edit mode to allow you to create new scenarios using existing simulation entities. Tutorials illustrate how to use the simulated sensors and also how to place multiple robots into the simulation environment simultaneously. Several sensors are available, including Compass, GPS, Brightness and Sonar. A rudimentary robot, without a 3D mesh, is used to show the basic principles of simulation. Robots can be placed into rich scenes such as an Apartment, House, Factory, Outdoor and Urban environments.
